Description
Technical field
The utility model relates to a kind of stationary installation, particularly relates to a kind of fixing block tongue for residual current type detector for electric fire protection.
Background technology
The fixed form of traditional residual current type detector for electric fire protection is all coordinated with erecting device by the mounting groove of its base to be fixed, may occur fixing unstable, hold caducous situation, then monitoring detection accuracy can be caused to reduce, affect fire hazard monitoring.
Utility model content
The purpose of this utility model is just to provide a kind of fixing block tongue for residual current type detector for electric fire protection to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of fixing block tongue for residual current type detector for electric fire protection, described detector comprises main body, base and Compress Spring, described main body is arranged on described base, wherein one side of described base is provided with the groove of the mounting groove perpendicular to described base, described block tongue is arranged in described groove, the dual-side of described groove is provided with stopper slot, the both sides of described block tongue are provided with the limited block corresponding with described stopper slot, described limited block can slide along described stopper slot, described block tongue is provided with strip through-hole, the bottom surface of described groove is provided with limited post, described limited post is arranged in described strip through-hole, and be positioned at the first end of described strip through-hole, the first end of described Compress Spring is fixedly connected with described limited post, second end of described Compress Spring is fixedly connected with the second end of described strip through-hole.
Particularly, the first end of described strip through-hole is curved end, and the radius of described curved end is greater than the radius of described limited post, and the width of described strip through-hole is equal with the radius of described curved end.
Preferably, described block tongue is provided with multiple hollow hole.
The beneficial effects of the utility model are:
The utility model is used for the fixing block tongue of residual current type detector for electric fire protection and is ejected by Compress Spring, makes its stationary installation with base side against fixing, makes its fixation, avoid it to occur coming off and cause monitoring out of true.
Accompanying drawing explanation
Fig. 1 is the perspective view for residual current type detector for electric fire protection described in the utility model;
Fig. 2 is the upward view for residual current type detector for electric fire protection described in the utility model;
Fig. 3 is the structural representation of block tongue described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of fixing block tongue for residual current type detector for electric fire protection, detector comprises main body 2, base 1 and Compress Spring 7, main body 2 is arranged on base 1, wherein one side of base 1 is provided with the groove of the mounting groove 9 perpendicular to base 1, block tongue 3 is arranged in groove, the dual-side of groove is provided with stopper slot 8, the both sides of block tongue 3 are provided with the limited block 4 corresponding with stopper slot 8, limited block 4 can slide along stopper slot 8, block tongue 3 is provided with strip through-hole 5, the bottom surface of groove is provided with limited post 6, limited post 6 is arranged in strip through-hole 5, and be positioned at the first end of strip through-hole 5, the first end of Compress Spring 7 is fixedly connected with limited post 6, second end of Compress Spring 7 is fixedly connected with the second end of strip through-hole 5, the first end of strip through-hole 5 is curved end, the radius of curved end is greater than the radius of limited post 6, the width of strip through-hole 5 is equal with the radius of curved end, block tongue 3 is provided with multiple hollow hole 10.
The principle of work that the utility model is used for the fixing block tongue of residual current type detector for electric fire protection is as follows:
Compress Spring 7 is when elongation state, and the distance between the end face of block tongue 3 and base 1 side is just, namely the end face of block tongue 3 is positioned at outside base 1; Compress Spring 7 is when compressive state, and the distance between the end face of block tongue 3 and base 1 side is negative, and namely the end face of block tongue 3 is positioned at base 1; When installing detecting device, block tongue 3 being pressed in base 1, Compress Spring 7 is compressed, after being inserted into fixed position, Compress Spring 7 extends, and applies outside acting force to block tongue 3, thus make block tongue 3 and stationary installation against, thus avoid base 1 to be moved, make its fixing-stable.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
